$0.00
Because lol @ anyone who buys anime and manga. The prices are outrageous and most of the time the DVD subs blow. Also, I'm not really interested in waiting 1-2 years to watch a new show.
But that's not to say I haven't watched/read quite a bit, in fact I'd challenge anyone to say they've seen more than I have
You can check my MAL in my sig

I would say more than 3000 €
I didn't count one by one, some of them are 7€ other are 15€, I round the price in between.
I don't read scantrad, I don't like reading book on a computer screen, I like the paper feeling.

Almost nothing on anime, I got disappointed on the first one I bought because of the subtitles (Official are so baddly done compared to fansub).

A decent amount of US dollars, around $700 over the course of ~8 years. I only buy what I want, some of it I got as gifts, and I hardly buy anything that I don't have coupon or is on sale. Best place to buy anime/manga is at the cons, especially on the last day since they're trying to clear out their inventories.

I don't read manga. The most manga I read is some that my friend keeps trying to lend me, and occasionally, it's available in the library, but even that I don't read much.

I don't really watch that many rare anime's, just more popular ones most of the time. So I just turn to dubbed ones. I don't need Jap w/ subs to watch Detective Conan and Jigoku Shoujo (which is the are the two animes I tend to follow, even though the second is already done and I just watch reruns which show very often). If there IS an anime that I like which I can't see on TV (KissXSis, Shadow Star, Black Jack, Rec), I turn to, of course, the internet.
